On some of my source image pages, the cards I have edited to be vertical still appear horizontal. Same thing with phone cases. It's like there's a template of how the product icons appear on that right hand side grouping even if you've changed the orientation on the product page. So maybe the WANELO choice of images is coming from how those small icons look on the source image page. Just a thought. I haven't linked any cards or cases on WANELO...I'm the Pillow Queen on there :)
